What relationship occurs between prey and another organism?
predator kills and eats prey for its survival. When the predator population increases, the prey population decreases because of too many hunters. When the prey population decreases, the predator population decreases because of the lack of food. Then, the prey population increases because there aren't that many predators and the process repeats itself.
What are Darwin's four postulates?
1. There is variation in individuals within a species 2. Variation ensures that individuals that are better suited to their environment will survive. 3. Traits that assist individuals in survival and allow them to reprduce gradually spread throughout population. 4. Individuals produce more offspring than the local resources can support.
Since species within ecosystem depend on one another, why don’t populations of species continuously grow?
As population size approaches The carrying Capacity Of the environment,the intensity Of density- dependent Factors Increases
What is the difference between discontinuous and continuous variation?
Continuous theory of matter says that matter comes in long continuous sheets,it never breaks while the discontinuous theory of matter assumes that matter comes in smaller packets and the reason why matter looks continuous is because we can't magnify it enough to see the small packets of matter. Continuous variation or continuous matter is gradual, something that is not so clear cut. For example, height can vary amongst population and there are many different heights. Discontinuous variation or matter is where you are either in one category or the other, but never in between. Examples of this are: Blood group - you are either O, A, AB, ABO but never anything in between. Another example would be tongue rolling - you can either tongue roll or you can't.
What effect does crossing over have on variation in a specie?
In crossing over the chomosomal segments of the homologous chromosomes get interchanged. Thus the genetic configuration of recessive and dominant genes gets altered and new gene combinations are formed which ultimately leads to the variation in the offsprings.
What is the meaning of variation in math?
In mathematics, variation refers to how a quantity changes in relation to another quantity. It is often described through concepts like direct variation, where one variable increases or decreases proportionally with another, and inverse variation, where one variable increases as the other decreases. Variation is essential in understanding relationships between variables in algebra, calculus, and statistics. It helps in modeling real-world phenomena and solving equations that involve changing values.
If the owl population increases what will happen to the number of voles and why?
If the owl population increases, the vole population will decrease. This is because there will not be enough voles for all of the owls. Then the owl population will decrease, therefore causing another increase in vole population.
What tends to increase genetic variation in a population?
Genetic variation is the total amount of genetic diversity present within a species or population. The amount of genetic variation in a population will depend on a variety of factors, including the size of the population, the type of reproduction, and environmental influences. The primary way to increase genetic variation in a population is through mutation. Mutations are random changes in the genetic code that can lead to new traits or characteristics. Mutations can be caused by environmental factors, such as exposure to radiation or chemicals, or they can occur spontaneously. Mutations can be beneficial, neutral, or detrimental to the organism, but they do lead to increased genetic variation. Another way to increase genetic variation in a population is through migration. When individuals from different populations mate, they bring with them different alleles from their home population, increasing the genetic diversity of the new population. This is especially important for populations that are geographically isolated, such as island populations. Another factor that can increase genetic variation is sexual selection. This is the process by which individuals select mates based on certain desired traits. This can lead to an increase in the number of different alleles in the population, as individuals with certain traits will be more likely to reproduce. Finally, gene flow is a process that can increase genetic variation in a population. Gene flow is when individuals from one population move to another population and mate with individuals in the new population. This can bring in alleles from the original population, increasing the genetic diversity of the new population. Overall, while mutation, migration, sexual selection, and gene flow are all important factors in increasing genetic variation in a population, it is important to note that genetic variation can also be decreased by inbreeding and genetic drift. Inbreeding is when individuals mate with close relatives, reducing the number of alleles in the population and leading to decreased genetic variation. Genetic drift is when random fluctuations in allele frequencies occur due to a small population size, leading to decreased genetic variation. Therefore, it is important to consider all of these factors when trying to increase genetic variation in a population.
What is another name for the constant of variation?
One other name is "coefficient of variation".

How does natural selection create a change in population over time?
By favoring one variation of organism over another variation in the same population. These favored individuals ( natural selection selects individual organisms ) leave more descendants, with these traits, who over time become more numerous in the population and the populations allele frequency changes to reflect this. In a word, evolution.
Can you name some endangered animals in India?
lion The asiatic lion. The current population is between 250 to 300 animals. Plans are to start another population in southwest India.
What is another variation of a prom chip?
socialization
What is the answer to theNumber of animals in a certain area?
It would be the population of an animal, you shouldspecify the animal if you would like to find the answer of that animals population in a certain area. It is the same with humans each state has a population and countries have them to another thing is etc.... hope that helped ya' bye.
Why do composers use variation?
A "variation" is just that ... a variation on the original theme, where the original tune or melodic idea is much the same, but the accompaniment may differ slightly or greatly. Another variation is to change the cantus firmus to another part, other than the soprano line, for instance.
What is a direct relationship in science?
In a direct relationship, a rise in x equals a rise in y while a drop in x results in a drop in y. Put another way, the two variables change in the "same way" with a variation in one followed by the "same kind" of variation in the other. Links can be found below.
